Get on board the NodeJS Express as we take a journey through what makes NodeJS special. Server-side JavaScript that has an event loop for a heart, we'll delve into its single threaded nature and the advantages provided. From there we'll pass through the land of the Node Package Management tool, how to set up your own package and bring in useful 3rd party packages as dependencies. Our final destination is ExpressJS, a Sinatra inspired framework for NodeJS.

Slides from my workshop about node.js which I conducted in Girl Geek Dinner Bangalore. More details at http://sudarmuthu.com/blog/introduction-to-node-js-at-yahoo-girl-geek-dinner
These are the slides of Tim Messerschmidt's presentation at LondonJS Conf 2014. They provide an overview about Kraken's main features and how to use them in practice.
Node.js and How JavaScript is Changing Server Programming Tom Croucher
Node.js is a highly concurrent JavaScript server written on top of the V8 JavaScript runtime. This is awesome for a number of reasons. Firstly Node.js has re-architected some of the core module of V8 to create a server implementation that is non-blocking (similar to other event driven frameworks like Ruby’s Event Machine or Python’s Twisted). Event driven architectures are a natural fit for JavaScript developers because it’s already how the browser works. By using an event driven framework Node is not only intuitive to use but also highly scalable. Tests have shown Node instances running tens of thousands of simultaneous users.
This session will explore the architectural basics of Node.js and how it’s different from blocking server implementations such as PHP, Rail or Java Servlets. We’ll explore some basic examples of creating a simple server, dealing with HTTP requests, etc.
The bigger question is once we have this awesome programming environment, what do we do with it? Node already has a really vibrant collection of modules which provide a range of functionality. Demystifying what’s available is pretty important to actually getting stuff done with Node. Since Node itself is very low level, lot’s of things people expect in web servers aren’t automatically there (for example, request routing). In order to help ease people into using Node this session will look at a range of the best modules for Node.js.

See our upcoming events at www.fitc.ca
OVERVIEW
We all love and adore JavaScript when we use it on the front-end of our web apps – why not use it in the back-end as well? That’s like having your cake and eating it too! Prepare to have your mind blown, because in this presentation we will create an entire web application using just (or well, mostly) JavaScript. Learn how to create a fast and flexible back-end utilizing the popular Node.js library and see how it ties in with your UI. From accessing the database to handling interactions with the front-end – we’ll do it all!

Developer, IBM @mhdawson1
You’ll have some captive Node.js/V8 collaborators, and you can ask them anything! Confused about the
LTS plans, wondering what is happening in the Node workgroups, want to know what is really going to
happen with Webworkers, what’s the future of Promises in Node.js? Wondering how to debug your
production failures? Ask us anything, and we’ll try and answer!
Node.js is coming up on its fifth year of existence and is clearly showing signs of maturity, from the core APIs becoming more stable, to the exponential growth of modules in npm to even a number of books being published to support the education needs of developers who want to learn Node. Node.js is officially past the infancy it was once in and is developing into a proper first class technology solution.
With this growth, there are growing pains. We have an exceptionally large and growing community of developers and now, enterprise companies who are adopting and actively supporting and contributing to Node. With this growth comes new challenges and new opportunities to strengthen the value propositions behind using and adopting Node.

Here's the showdown you've been waiting for: Node.js vs Play Framework. Both are popular open source web frameworks that are built for developer productivity, asynchronous I/O, and the real time web. But which one is easier to learn, test, deploy, debug, and scale? Should you pick Javascript or Scala? The Google v8 engine or the JVM? NPM or Ivy? Grunt or SBT? Two frameworks enter, one framework leaves.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Builder.ai Founder Sachin Dev Duggal's Strategic Approach to Create an Innova...Ramesh Iyer
In today's fast-changing business world, Companies that adapt and embrace new ideas often need help to keep up with the competition. However, fostering a culture of innovation takes much work. It takes vision, leadership and willingness to take risks in the right proportion. Sachin Dev Duggal, co-founder of Builder.ai, has perfected the art of this balance, creating a company culture where creativity and growth are nurtured at each stage.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

15. What does the code look
like?
var fs = require('fs');
var rawData = fs.readFileSync('sotr.json');
var data = JSON.parse(rawData);
console.log(new Date());
console.log(data.message);
16. Why not just be multi-
threaded?
Each thread needs more
memory
Switching between threads
costs CPU
Avoids thread safety issues
18. var cluster = require('cluster');
var http = require('http');
var cpus = require('os').cpus().length;
if (cluster.isMaster) {
for (var i = 0; i < cpus; i++) {
cluster.fork();
}
cluster.on('exit', function(worker, code, signal
console.log('Process ID ' + worker.process.pid
});
} else {
http.createServer(function(req, res) {...}).list
}
22. Node as a web
application
var http = require('http');
var server = http.createServer(function(req, res)
res.end('Hello Scotch!');
});
server.listen(80);
23. Modules
// conf.js
function Conference(name, year) {
this.name = name; this.year = year;
};
Conference.prototype.getTitle = function() {
return this.name + ' ' + this.year;
};
module.exports = Conference
// index.js
var Conf = require(__dirname + '/conf.js');
var sotr = new Conf('Scotch on the Rocks', 2014);
console.log(sotr.getTitle());
27. Common modules
Databases: mysql, mongodb,
sqlite
Callbacks: async, q, when, co
Testing: Mocha, nodeunit,
should
Templating: Jade, handlebars,
ejs
Web frameworks: express,
31. Summary
Let npm manage your modules
Use it to install useful tools
such as grunt
Don't have to keep
node_modules in source
control
Store project related
commands in package.json
33. Version 4
Bundled middleware are now
their own modules*.
* Except "static".
More robust routing.
app.router()is gone and
more flexible methods are now
available.
